Page 1 of Minato G1: Sound on Chinese VCDs?

I recently got this machine because of it`s ability to play CDR VCDs. I previously had a Samsung 809 thats only downfall was its inability to do so.

However I have a few original Chinese VCDs (Jackie Chan, Chow Yun Fat etc). These are subtitled with the original language in one stereo channel and I think Mandarin in the other. With the Sammy I could choose which language to listen to while watching by switching the channel from stereo to either left or right.

The problem I have with the Minato, which otherwise i am well pleased with, is that I cannot find such an option in the menus. Therefore I have to listen to the two languages at the same time! This basically makes the movies intolerable as it is very annoying!

Anyone have any idea what I could do to stop this from happening?
